1. Introduction

The HB170 miniature microwave motion sensor is an X-

Band Bi-static Doppler transceiver module. These modules

are designed for applications in movement detection and

speed measurement.

The module consists of a Dielectric Resonator Oscillator

(DRO), mixer, patch antenna array , and an added Low Noise

Amplifier (LNA) at the receiver to achieve longer detection

range.

This User Manual highlights some important points for

application with HB 7 series modules.

2. Mounting

Header pins can be used to connect the terminals (V1, V2, IF, GND) to the power supply and the

amplifier circuits to serve as mounting support. Other mounting methods may be used. Caution must be

taken to avoid pressure or stress being applied to the chassis of the module as it may cause performance

deterioration.

V3: NC (NOT CONNECTED); 5. IF: Doppler Shift Output 4. Pulse Operation The Pulse operation of Transmitter (V1) uses +5Vdc pulsed at up to 2kHz repetition frequency at a duty cycle of 5% for lower power consumption. The Pulse operation for the Receiver (V2) is not recommended. It is only operated at a supply of +5VDC.

X-Band Microwave Motion Sensor Module HB170 Users Manual V1.00 5. Transmit Frequency The transmit frequency and power of the module is set by the factory. There is no user adjustable part in this device. The module is a low power radio device (LPRD) or intended radiator. Local radio communication authority regulates use of such a device. Though user license may be exempted, type approval of equipment or other regulation compliance may be required. Annex 1 shows the allocated frequency in some countries.

X-Band Microwave Motion Sensor Module HB170 Users Manual V1.00 The 93dB loss is the total losses combining two ways free space loss (82.4 dB for 30 meters at 10.525 GHz), reflection loss and absorption loss of the target, as well as other losses. This RSS figure can be viewed as an approximation of the output signal strength for a human at 15 meters away walking straight to the module at 1.28 km/hour.

If a target is moving straight toward or away from HB100 (Ft = 10.525 GHz) The formula is simplified to: Fd = 19.49V (Velocity in km/hour) or 31.
